Dear Josh:

We would like very much to have copies of the
Boivin strains which I understand you have. What
we need are copies of the transformable rough and the
smooth.

At one time Tatum sent them to Hershey, who
prompt ly threw them out.

No news fran here which is worth spending much
tine on. How's by you?

Sincerély yows,
Se Spiege Iman
